To all whom it may concern:

Be it known that we, JOHN H. K003 and WILLIAM J. LARSEN, citizens of the United States, and residents of San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in' Book- Making Machines, of which the following is a specification.

The object of the present invention is to provide a machine for gluing backs or covers to the bodies of magazines or books which will operate automatically and without any care or attention except that of feeding said covers and bodies thereto, and which can be adjusted for operating on magazines or books of different thicknesses, the present application being a division of an application filed by us Sept. 17, 1918, Ser. 1%. 25am In the accompanying drawing, Figure 1 is a side view of our improved gluing machine; Fig. 2 is a plan view thereof; Fig. 3 is a front end view thereof; Fig. 1 is a partial vertical section on the line 4:1 of Fig. 2; Fig. 5 is a vertical cross section on the line 5-5 of Fig. 2; Fig. 6 is a similar view on the line 66 of Fig. 1; Fig. 7 is a similar view on the line 7-7 of Fig. 2; Fig. 8 is a horizontal section on the line 88 of Fig. 9; Fig. 9 is a transverse vertical section on the line 99 of Fig. 1; Fig. 10 is a horizontal section on the line 10-10 of Fig. 9; Fig. 11 is a transverse vertical section on the line 1111of Fig. 1; Fig. 12 is an enlarged detail vertical longitudinal section on the line 1212 of Fig. 3; Fig. 13 is a side view of a detail of construction.

Referring to the drawings, 1 indicates uprights supporting a horizontally extending rectangular frame 2, upon which is secured a longitudinally extending table 3, narrower than the frame, said table projecting behind the rear or feed end of the frame. Upon said projecting end of the table are supported rectangular upright frames 41-. to the upper portions of which are secured, by screws 6 a feed table 7. Said feed table 7 is formed with a longitudinally extending open-ended slot 8, opening through the front edgeof the table, and depending from said table in said slot are walls 9, 10, which serve as guides below the feed table. The book or magazine bodies to which the cover is to be glued are placed in a plle on the feed table '7 to the right of the slot, and are fed by hand, one at a time, into said slot or guideway and between said gu des. A wall 10 on one side of the slot 8 is extended forwardly, as shown at 15. and in front of the wall 9 on the other side of the slot is a wall 14, said wall let and extension 15 being extended upwardly above the feed table 7. The wall 1 1 is ad'i'ustable to and from the extension 15 by means of an angular upright secured to the wall lt and having a slot through which passes a screw 30 secured into the tablo3, saidupright also having a rightangled extension 13, which is adjustably screwed to the table 7 by a screw 11 passing through a slot 12 in said extension 13 and screwed into the edge of said table 7. Secured t0 the upwardly extending portion of the extension 15 by a corner piece 20 is a wall 16, extending at a right-angle to the said slot 8, and serving to brace the table 7 and as a protector and guide for the front edges of the magazine or book bodies. An angular protector 17 is also secured to the upper portion of the wall 1 1. i

The lower edge of the magazine or book body deposited through said open-ended slot drops upon a belt 18 which travels around three rollers 19 on shafts 21 in pairs of bearings 22 secured to the table, the rearmost pair of bearings being adjustable, to tighten the belt around the rollers, by means of screws 23 screwed through downwardly extending front ends of plates 21 upon which said rear bearings are supported, and which plates are secured to the table 3, the

forward ends of said screws abutting against the rear edge of said table 3. The shaft 26 in the foremostbearings extends also through a bearing 27 and carries on its outer end apinion 28,which meshes with a gear wheel-29, which in turn meshes with a gear wheel 31 on a transverse shaft rotating in bearings 33 depending from, and secured to the underside of, the frame2. On an end of said shaft 32 is secured a wheel 3d around which travels a belt 36 which also travels around a shaft 37 of a suitably supported electric motor 38. By the rotation of theshaft 37, and, therefore,

I also of the shaft 32, and the forward movesaid shaft 71 around which travels the magazine or book body is carried for wardly and its advancing edge passes between a pair of vertical rollers 39. The shafts 40 of these rollers have their bearings in upper and lower horizontal plates 41 extending inwardly from castings or uprights 42, having angular lower ends secured to the upper surface of the table 8.

The left-hand one of the pair of shafts 40, looking in the direction of advance of the magazine bodies, extends downwardly through saidtable 3 and carries on its lower end a miter gear 43, (Fig. 9), which meshes with a miter gear 44 on said transverse shaft 32, and thereby said vertical shaft 40 is 1'0- tated. 1t imparts rotation to the other shaft 40 by means of gear wheels 46 on said vertical shafts 40 which mesh respectively with intermediate gear wheels 47,fwhich mesh with each other. The shafts 45 of said gear wheels 47 are adjustably secured by bolts 50, and washers 55 in slots in a casting secured to the under side of the table 3. Also having bearings in said upper and lower plates 41 are shafts 48 of a pair of rollers 49 (Fig. 1) between which the magazine bodies pass after passing between the pair of rollers 39. All of the rollers be tween pairs of which the magazine bodies pass have their surfaces of rubber or other yielding material.

Said shafts 48 are rotated from the shafts '40,. (Fig. 8) by gear wheels 51, 52, on said shafts 48 and 40, and intermediate gear wheels 53 meshing with said gear wheels 51, 52. Thesewheelsol, 52, are located between the table 3 and the plates 41.

The upper ends of the shafts 40 carry miter gears 54 which mesh with miter gears 56 onlongitudinally and horizontally extending shafts 57, 57 having bearings in uprights 58 extending upwardly from the upper plates 41.

Further advanced portions of the shafts 57, 57', (Figs. 1, 2), carry miter gears 59 which mesh with miter gears 61 on vertical shafts 62 carrying another pair of vertically extending rubber rollers 63, said shafts 62 having upper and lower bearings in plates 64, 66 extending inwardly from castings 68 secured on the table 3 and similar to the castings 42. By means of said pairs of rollers 39, 49, and 63, said magazine bodies are advanced so that their lower edges travel in contact with the upper surface of a gluing roller 69 on a shaft 71, and which retates in an open-topped glue-pot 72. Said glue pot is maintained, hot by having its lower part immersed in a water container 73, (Fig. 11), in which water is heated by an electric heater 7 4 to which wires 76 lead from any suitable source of electricity. Said gluing roller is positively rotated by means of a grooved wheel 77, (Figs. 2 and 4) on. round band 78 which also travels around a grooved wheel 7 9 upon the transverse shaft 32.

In order that it may be insured that they pass between the rollers (33, the outer leaves of the magazine or book body are prevented from spreading, when passing over said gluing roller, by means of spring metal guide plates 81, (Figs. 1, 2), secured to the uprights 42, extending forwnlrdly therefrom and converging toward their front ends, so as to press the leaves of the magazine or book body together as it passes therebetween.

By the above means the magazine body is fed in succession into the spaces between three pairs of rollers 82 on vertical shafts 83. The rollers on the right hand side are driven by means of the longitudinally extending shaft 57, which has thereon miter gears 84 meshing with miter gears on the upper ends of the right hand vertical shafts 83. Said latter shafts 88 have upper and lower hearings in plates 87. 88, extending inwardly from a vertically directed and longitudinally extending plate or casting 89, having lower horizontally extending portions 91 secured upon the table 8.

In order to adjust the machine for magazinc or book bodies of different tlliekiiesses. the castings 42, 6S, and 89 which support the bearings for the long shaft 57 are slidable transversely of said shaft 57. being guided by guides 92 secured on said table 3, and are secured by bolts 98 which extend ln'ongh transversely extending slots 9-1- in the table 3.

The shafts of the rollers 82 on the left hand side of the machine carry at their upper ends miter gears 96, which mesh with miter gears 97, (Fig. 1), on a horizontallv and longitudinally extending shaft 98 normally in alinement with the shaft 57, and having bearings in uprights 99 extending upwardly from a casting 101 which has apertured ears 103 supporting a shaft 102. which has bearings 104 in the left-hand easting 68 and in a standard 106 secured to the table 3. Said shafts 98 and 102 derive their motions in the following manner :-On the lower portion of the rearmost left-hand shaft ()2 (Fig. 11) is a miter gear 10? which meshes with a miter gear 108 on a horizontally and longitudinally extending shaft 100. (Figs. 3, 6), carrying a roller 111, whit-h shaft 109 also carries a gear wheel 112 which meshes with a gear wheel 113 upon the shaft 102. Said shaft 102 also carries a sprocket wheel 114, (Figs. 1, 0). around which travels a sprocket chain 110 which also travels around a sprocket wheel 117 on said shaft 98. Above the roller 111 is a roller 118 on a shaft 119, (Fig. 7). carrying a gear wheel 121 which meshes with a gear wheel 122 on the shaft 102. By this means said roller 118 is rotated.

On the righthand side of the machine and cooperating respectively with the rollers 111, 118 on the left-hand side, are horizontal rollers 123 and 124, the lower one 123 of which derives its motion from a miter gear 126 on the rear end of its shaft, (Fig. 11), meshing with a miter gear 127 on the shaft 62 of the right-hand roller 63. The upper roller 124 derives its motion from the lower roller 123 by means of gear wheels 128, 129, (Figs. 7 and 3), on shafts of said rollers and an intermediate gear wheel 131 upon a stud shaft extending from a plate 132 secured to the casting 89 and movable therewith.

hen the magazine body is fed between the three pairs of vertically extending rollers 82, its lower edge lies between the rollers 118 and 124, but is out of contact therewith, so that it can be moved freely in a longitudinal direction between the three pairs of vertically extending rollers. The rollers of the vertically extending pairs of rollers 82 are then caused to separate from each other by means of a cam 133, (Figs. 1, 2,3), ona shaft 134 mounted in a bearing 136 upon a post 137 secured to the adjustable plate or casting 89, and adjustable vertically thereon by means of screws 135 (Fig. 13) through slots 140 in said post, screwed into said casting 89, which shaft 134 also carries a gear wheel 138 meshing with a pinion 139 on the longitudinally extending shaft 57 Thereby said cam shaft is rotated. In its rotation the ram 133 presses against a cam roller 141 on a shaft 142 secured upon an arm 1-13 adjustably secured by a set screw 144 in a slot 146 in the upper end of a post 147 secured to the vibratable casting 101. Said cam roller is drawn toward said cam by means of acoiled spring 148 of which one end is secured to the set screw 144 which secures in place the arm 143 and the other end is secured to a set screw 151 which secures in place the shaft 134.

fit the proper time, therefore, in the operation of the machine, the vibratable casting 101, carrying with it the vertically ex tending rollers 82 on one side of the machine, is vibrated byithe cam 133, and thereby the magazine body-is no longer pressed between the pairs of vertical rollers 82, but drops, and its lower edge, having thereon the requisite quantityof glue received from the gluing roller 69, drops onto a cover, which, by mechanism now to be described, has been moved into the position proper to receive said glued edge.

In order to insure that each magazine body will arrive at the proper time between the rollers 82, and the vibratable frame 101 will be vibrated at the proper time to perniit the magazine body to drop, the magazine bodies are in succession arrested in their movement on the belt 18 by a finger 100 (Fig. 2) which extends in front of the space between the wall 14 and extension 15, and is bent inwardly from an arm 105, which extends through a recess in the front edge of the wall 15, said arm being bent horizontally from the lower end of a rod 110, the upper end of which is secured upon the rear end of a shaft 115, having its bearings in the ends of upwardly bent ends 120 of a bar 125, secured to the uprights 42, 63, there being secured to said shaft 115 an arm 130, which, in the rocking movement of the shaft 115, is arrested by said bar 125, and forms a step for arresting said rocking movement. The front end of said shaft 115 is bent to form an arm 155, (Fig. 1), which extends closely adjacent to the rear surface of the gear wheel 138, and is adapted to be engaged by a roller 160 on a pin 165 adjustably secured in an arcuate slot 170, (Fig. 3), of said gear wheel. At the proper time in the rotation of the gear wheel 138, said roller actuates said arm 155 to rock the shaft 115, and withdraws the finger 100 from in front of the front edge of the mag azine which is supported by the traveling belt 18 and permits said magazine to advance.

152 indicates a cover feed table, extending in a direction transverse to the general direction of the machine, and supported by a suitable frame 154 adjacent to the rear end of the gluing machine and having secured thereon a guide wall 153. The covers are fed by hand onto endless belts 156 which travel around rollers 157 on shaft 158 carried by arms 159 adjustably secured by screws 161 passing through slots 162 in said armsand screwed into said frame 2, said belts also passing around grooved portions 163, (Figs. 4, 6), of the lower horizontal roller 123.- A flat strip 164, (Figs. 2, is located midway between, and at the same level as, said belts 156 and its ends are bent down and secured, at one end to the rear edge of the frame 2, and at the other end to the table 3, (Figs. 2, 4). On the under side of the strip 164 is secured a transversely extending support 168 over which the belts 156travel, the cover being held down to said belts by rollers 169 rotatably supported in the ends of arms 172, the other ends of which are pivoted upon the bent ends of arms 173, the other ends of which are adjustably secured upon the bent ends of wire supports 174. Springs 176 coiled around said arms 173 depress the arms 172 and the rollers 169 carried thereby.

It will be evident that said belts are caused to travel by the rotation of said roller 123. By this means each cover in sun cession. is fed between said horizontal rollers 123 and 124 and also between the pairs of opposite rollers 111, 118, and onto a table 178 supported over the table 3, (Fig. 6),

, the cover abuts.

casting 101 vibrates.

and having adjustably secured thereon, by means of thumb screws 179 through slots 181, stops 182 having vertically extending portions against which the forward end of The cover has now been brought to the proper position to receive on its central portion the glued lower edge of the magazine body brought to the proper position by the'means described.

When said body drops on to said cover it is immediately thereafter clamped by the upper roller 118 pressing against the upper roller 124:, said upper roller 118 being located below the shaft 102 on which the By the vibration of said casting by means of said cam 138, said roller 118 is moved inwardly at the same time that the upper portion of the casting and the vertical rollers 82 therein are moved outwardly. Thereby and by the downward motion of the inner sides of the rollers 118 and 124:, the magazine body and the cover are positively drawn down and are caused to pass between the lower rollers 111 and 123, and by the continued rotation of said rollers, the magazine, with the cover glued thereto, is drawn downward. It is guided in its downward movement, between said lower rollers, 111, 123, by means of two pairs of upwardly extending roos 18S,

(Figs. 1, 6), having pointed upper ends the lower portions of said rods being secured in a plate or casting 18% supported upon an intermediate frame 186 and extending therefrom first upwardly and tl rough holes in flat bars 18? bent downward at the ends and secured to said casting 181-, then inwardly over a belt 188 and then upwardly again. The pairs of rods, on opposite sides of the belt 188, are so located that the magazine or book is guided downwardly until its lower edge is in contact with'said belt. The middle portion of said belt, with which the magazine is in contact, is supported on the under side by a roller 189, the shaft of which is rotatably supported at its ends in standards 191 upon the bars 187.

Said belt travels around rollers 192, and

the shaft 198 of one of said rollers carries a sprocket wheel 19% by which it can be rotated, said sprocket wheel having therearound a sprocket chain 196, which also passes around a sprocket wheel 19? upon the transverse shaft 82.

The completed magazine or book is thus conveyed by said belt between a. pair of Vertical rollers 198, on shafts 199 which are rotated by means of miter gears 201 thereon (as shown in @Fig. 3) meshing with miter gears 202 on a shaft 203 rotating in bearingsQOd, in a plate 206 and in one of the supports 207, and carrying a gear wheel 208 which meshes with an intermediate gear wheel 209 which meshes with a gear wheel 211 on the shaft 193. The magazine or book then passes between another pair of rollers 180, rotated by gear wheels 185 on heir shafts, meshing with intermediate gear wheels 100, on vertical shafts 105 having their lower hearings in the supports and their upper in brackets 200 secured to said supports, which gear wheels 190 mesh with gear wheels on the shafts 109.

The middle portion of the cover, which surrounds the lower edge of the magazine, and is adjacent to its glued portion has up to the present time received only a rounded form. It is necessary to give this portion of the cover a square or angular form, to conform to, and lit closely against. the lower edge of the magazine body. For this purpose there is bolted to the plate 184-. as shown at (Fig. 12) a block 21?. through a zcntral hole in which exlends upwardly a round bar :?1:. the lower end of which is threaded. and screwed on said threadml lower end is a nut 216 which is received in a hole in the under side of said block. The upper end of said bar carries a support 217, from which extend upwardly arms 218, between which is rotatably carried a shu l't Bl!) carrying disks spaced from each other a distance substantially equal to the thickness of the magazine at its gununed edge. the inner or opposing faces of said disks having beveled edges. From said support 21 T rods 222 extend first longitudinally and then downwardly and into holes 223 in the block. and thereby prevent the turning of the support 217 about said bur 21-1; as a vcrl'iral axis. A spring 221- IS coiled around said bar and compressed between said support 214 and said block 913. and normally raises said support. Said block is so placed that the disks are located to receive the edge of the completed magazine as it comes from the foremost roller. the lower edge of the magazine body first entering the upper portion of the space between said disks and pressing); said support 217 and disks downwardly against the pressure of the spring" 22-1- which acts to press the middle portion of the cover close to the sides of lhe magazine to change the edge of the magazine from a rounded to a rectangular form.
